If you add up all the costs to upgrade the OEM heads, valves, springs, bronze valve guides, roller rockers and various machining they come out more expensive than modern alloy cylinder heads.
The only advantage of keeping the OEM cylinder heads is to keep the original look and then I like the idea of getting a lot of horses out of an "old" engine with its "old" all-cast iron cylinder heads. That's the reasons I'm going to keep them on my engine.
